    摘要： A method relative to an optical information storage medium including a lead-in area, a lead-out area, and a user data area between the lead-in and lead-out areas and in which user data is recorded. Pits are formed in the lead-in area, the user data area, and the lead-out area, and a track pitch in all or a portion of the lead-in area is different from a track pitch in the remaining area of the optical information storage medium.

    摘要： A disc having grooves and pits with different depths according to λ/8n≦d3≦λ/5n where d3 is a difference in depths between the grooves and the pits, λ is the wavelength of a light source, and n is the refractive index of the disc. A disc having grooves and pits with different depths can be manufactured without etching by using at least two stampers. Manufacturing a master by depositing photoresist over a glass master, forming a first land region and a second land region having different depths by laser cutting with laser beams having different power levels. Stamping a father stamper having a groove region and a pit region from the master, the shape of the father stamper inverse of the master. Stamping a mother stamper from the father stamper, the shape of the mother stamper inverse of the father stamper. Manufacturing the disc with the mother stamper.

    摘要翻译： 根据<？in-line-formula description =“In-line formula”end =“lead”？> lambda / 8n <= D <3> <= lambda，具有不同深度的凹槽和凹坑的圆盘 / 5n <？in-line-formula description =“In-line Formulas”end =“tail”？>其中d <3> 是凹槽和凹坑之间的深度差，λ是波长 的光源，n是光盘的折射率。 具有不同深度的凹槽和凹坑的圆盘可以通过使用至少两个冲压机而不进行蚀刻来制造。 通过在玻璃母板上沉积光致抗蚀剂来制造母版，通过具有不同功率水平的激光束激光切割形成具有不同深度的第一接合区域和第二接地区域。 压印具有沟槽区域和凹坑区域的父母压模，父母压模的形状与母版相反。 从父亲压印母印机，母模的形状与父亲压模相反。 用母模制造光盘。
